About support USB3.0 LTM(Latency Tolerance Messaging)

[zhaoqiao]

Hi all,

  I have a problem. In commit 024f117...  said "USB: Add a sysfs file to
show LTM capabilities."
speak about "+What:          /sys/bus/usb/devices/.../ltm_capable", but i
not found ltm_capable.
Related information not found in the source code, maybe i'm missing
something. :(
Can you give me some help?
